Dawn Spacecraft Heads for Ceres

It's going to be a ball when NASA's Dawn spacecraft finally arrives at the dwarf planet Ceres, and mission managers have now inked in the schedule on Dawn's dance card.

Dawn Spurs Rewrite of Vesta's Story

Just when scientists thought they had a tidy theory for how the giant asteroid Vesta formed, a new paper from NASA's Dawn mission suggests the history is more complicated.

The Great Atlas of the Giant Asteroid Vesta

An atlas of the giant asteroid Vesta, created from images taken as NASA's Dawn mission flew around the object (also known as a protoplanet), is now accessible for the public to explore online.

Traveling from one alien world to another, Dawn is reliably powering its way through the main asteroid belt with its ion propulsion system.

A Shared Bombardment History

From NASA ,scientists have now discovered that studying meteorites from the giant asteroid Vesta helps them understand the event known as the lunar cataclysm, when a repositioning of the gas giant planets destabilized a portion of the asteroid belt and triggered a solar-system-wide bombardment.

Dawn Sees 'Young' Surface on Vesta

Like a Hollywood starlet constantly retouching her makeup, the giant asteroid Vesta is constantly stirring its outermost layer to present a young face. Data from NASA's Dawn mission show that a form of weathering that occurs on the moon and other airless bodies we've visited in the inner solar system does not alter Vesta's outermost layer in the same way.

NASA's Dawn spacecraft has revealed the giant asteroid Vesta has its own version of ring around the collar. Two new papers, based on observations from the low-altitude mapping orbit of the Dawn mission, show volatile, or easily evaporated, materials have colored Vesta's surface in a broad swath around its equator.

Vesta in Dawn's Rear View Mirror

NASA's Dawn mission is releasing two parting views of the giant asteroid Vesta, using images that were among the last taken by the spacecraft as it departed its companion for the last year.

Activities for new Expedition 31 crewmembers, Soyuz Commander Gennady Padalka, NASA Flight Engineer Joe Acaba and Flight Engineer Sergei Revin include a pre-launch fit check in a Soyuz capsule at the Baikonur Cosmodrome in Kazakhstan, the raising of flags outside the Cosmonaut Hotel crew quarters and launch to the orbiting laboratory to meet up with NASA Astronaut Don Pettit, Cosmonaut Oleg Kononenko and Andre Kuipers of the European Space Agency.

Dawn Reveals Vesta

NASA Dawn mission researchers undertaking the first global analysis of the giant asteroid Vesta have looked back at the history of our solar system and found evidence of surprisingly recent collisions that left large impact basins.

Dawn Reveals Secrets of Vesta

Findings from NASA's Dawn spacecraft reveal new details about the giant asteroid Vesta, including its varied surface composition, sharp temperature changes and clues to its internal structure. The findings were presented today at the European Geosciences Union meeting in Vienna, Austria, and will help scientists better understand the early solar system and processes that dominated its formation.

Dawn Gets Extra Time to Explore Vesta

NASA's Dawn mission has received official confirmation that 40 extra days have been added to its exploration of the giant asteroid Vesta, the second most massive object in the main asteroid belt. The mission extension allows Dawn to continue its scientific observations at Vesta until Aug. 26, while still arriving at the dwarf planet Ceres at the same originally scheduled target date in February 2015.
